Title: Production of syndiotactic 1,2-polybutadiene and catalyst composition based ion iron used for the same
Inventor: LUO STEVEN
IPC: C08F136/06
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a syndiotactic 1,2-polybutdiene and to produce a catalyst composition based on ion therefor. SOLUTION: This catalyst composition suitable for use when polymerizing 1,3-butadiene and producing a syndiotactic 1,2-polybutadiene comprises (a) an iron-containing compound, (b) a dihydrocarbyl hydrogenphosphite and (c) an organoaluminum compound. The use of an environmentally hazardous component, e.g. carbon disulfide and a halogen-substituted solvent is avoided by using the catalyst composition. The melting temperature of the syndiotactic 1,2- polybutadiene can be changed within the range from about 100 to about 200 deg.C by changing the catalyst components and the componental ratio. It is extremely favorable that the melting temperature can be changed within the wide range by using the simple catalyst composition. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for a rubber composition.  In this case, syndiotactic 1,2-polybutadiene can be crosslinked together with a usual rubber using a usual crosslinking agent.

Title: Method for measurement of dc polarization curve
Inventor: MOCHIZUKI NORIYASU
IPC: G01N27/416
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To measure a polarization curve while a solution resistance is being corrected in real time. SOLUTION: In this method, the DC polarization curve of a sample 1 is measured by using the sample 1, a counter electrode 2 and a reference electrode 3. A potential and a current across the sample 1 and the reference electrode 3 are measured. After that, an AC voltage is superposed across the sample 1 and the counter electrode 2. An impedance across the sample 1 and the reference electrode 3 is measured. After that, the AC voltage is released. A solution resistance is found on the basis of the found impedance. While the solution resistance is corrected repeatedly with reference to the potential which is measured immediately before the AC voltage is measured, the DC polarization curve is measured.
